One of the key skills of a software developer is inference and you guys need to go get some more coffee and come back and try reading this thread again.
For code only, even then only sometimes or even rarely. The HN comments section is like a gold mine of the Dunning Kruger effect for social awareness/intelligence. It's not even worth pointing out because you'll just get 5 paragraphs in response of "no, you're wrong because I'm smart and so I'm right". It's exhausting.
It seems more like you’re exhibiting “redditor behavior”. Ostensibly, the comment you replied to was about TFA, and you replied flippantly with a statement of fact “you can’t walk to a data center” when the discussion is about an article related to a data center in a residential area. They didn’t pull a “gotcha”, you got got by your own ignorance of the topic at hand.
You obviously have never been to Ashburn, Virginia. Look up Lord Fairfax Pl. in Ashburn, VA on Google Maps and note the data center just outside that neighborhood.
